Summary
Statistics is a branch of mathematics. Students get practice with multiple-choice questions on statistical tests and data interpretation.
Types of tests
Statistical tests can be one-tailed or two-tailed. One-tailed tests check if a value is above or below a certain point. Two-tailed tests check if a value is different from a certain point.
Hypothesis testing
Hypothesis testing involves comparing observed data with a predicted outcome. This process helps to determine whether to reject or fail to reject a null hypothesis.
Interpreting statistical data
Interpreting statistical data involves understanding signs and symbols. These signs and symbols show the relationship between observed data and predicted outcomes.
Practice questions
Practice questions cover a range of statistical concepts. These questions help students to apply statistical methods to real-world data.
